The present invention relates to a fishing buoyancy used for fishing, and in particular, a sealing portion having a plate-shaped sealing plate and rod-shaped first and second support rods connected to the upper and lower surfaces of the sealing plate, respectively. And an upper cap that is hollow and has a first through hole on one side of its upper surface, and a hollow semi-circular shape that has a second through hole on one side of its upper surface. Both the lower cap with the through hole and the upper and lower space, which is the space created by the upper and lower caps and the sealed portion to adjust the buoyancy required by the user when fishing. Alternatively, in order to prevent water from leaking from the water storage unit to the outside of the upper and lower caps, the water storage unit into which a water tank for filling water is inserted in either of the spaces, and the first and second support rods. The buoyancy-adjusting fishing tackle is provided with a hermetically sealed packing portion inserted into one side, respectively, and the hermetically sealed packing portion is hermetically inserted into the first and second through holes, respectively. [Selection diagram] Fig. 1本発明は、釣りに用いられる釣りウキに関し、特に、板状の密閉板を有し、前記密閉板の上下面のそれぞれに棒状の第１及び第２の支持棒がそれぞれ結合されている密閉部と、中空の半円状であり、その上面の一方の側に第１の貫通孔が穿設されている上部キャップと、中空の半円状であり、その上面の一方の側に第２の貫通孔が穿設されている下部キャップと、使用者が釣りをする際に必要とする浮力を調整するために前記上下部キャップと前記密閉部とによって生成された空間である上下部空間の両方またはどちらか一方の空間に水を満たすための水槽が挿入される貯水部と、前記貯水部から前記上下部キャップの外部に水が漏れ出ることを防ぐために、第１及び第２の支持棒の一方の側にそれぞれ挿入された密閉パッキン部と、を備え、前記密閉パッキン部は、前記第１及び第２の貫通孔にそれぞれ密閉挿入されることを特徴とする浮力調整釣りウキを提供する。【選択図】図１
